Wemos LOLIN32 ESP32

Description:
Remember the NodeMCU - The ESP8266 based development board that pioneered the current IoT boards? - Meet its mother.
The LOLIN32 is very similar to the NodeMCU, taking on the same form factor and general pinout layout. It contains WiFi, Bluetooth but also includes a JST Connector for charging single cell lithium-ion batteries.
This deals with issues that many are facing with trying to pair ESP8266 devices + Lithium Chargers. Here we have this all on 1 board with a much more powerful processor.

Applications:
- IoT Sensor Monitoring - Temperature, Moisture, Waterlevel, etc
- WiFi Communication for backup alarms
- Applications requiring portable communication
- Tracking (with added GPS)
